PHASE DOPPLER ANEMOMETRY FOR BALANCING AND MODELING OF MULTIPHASE FLOW

Diffraction, refraction, and reflection are components of the light scattered on interaction with dispersed systems. They lead to differing measurable phenomena and are utilised for the characterisation of particle properties in multiphase flow. The property of greatest interest is the particle size. Contact- and reaction-free optical laser measuring methods suitable for in-line measurements. such as phase Doppler anemometry, utilise light scattered by the particles in order to determine their size and velocity, and also to some extent for the determination of other dispersion-related or kinetic particle properties. This is illustrated for the case of phase Doppler anemometry.
